The decryption part is not the case that exiting immediately.
What I observed here is that:Įncryption returns SUCCESS, output length 256, but content is NOT the same with the given one.īoth public key and private could be used in the encryption part, with a SUCCESS return. This thing also happened when I using the lib downloaded from st.com, using the keys and sample ciphertext in the lib's sample project file, configuring a STM32F401VE board and running rsa_pkcs1v22. However, after checking step by step during the simulation, the encryption for RSA could return a SUCCESS, but the decryption part always returns a FAIL. In the Proteus 8 I chose a board of STM32F401RE connected with an LED light to debug. Currently I am using the x-cube-crypto and STM32F401RE-Nucleo to do simulation. I'm new to the STM32 MCU and simulating RSA encryption-decryption on Proteus 8 now.
